Differentiae are written after each antiphon and were identified in the original Cantus index by their last note and a numeral to distinguish between differentiae that end on the same pitch within the same mode. The Cantus index was incomplete at the time of the manuscript's addition to the differentiae Database, so its tonary will need to be updated accordingly.
